I assume it all depends on what you're going for. Better performance or better eco. I'd call hypertech themselves for the best explanation.

The fact that they have a completely seperate tuner for better eco is retarded. If you waited for diablo sport I'm sure the customer tuner could write you a performance tune and a pure economy tune. Requardless, you should see increased eco with a tuner

Thanks man, that's what I figured.. I actually just received a response from Hypertech.
-----------------------------------------------------------------You’ll want the 52501 Max Energy it has a lot more options and there is very little cost difference. The Econ version 53501 has one option only which is our tuning for regular octane fuel to help increase power and to help mileage. The 52501 has the same regular octane tuning plus our tuning for premium, if the premium option is used you’ll need to use no less than 91 octane. You get a little more power out of the premium tuning as compared to the regular setting.-------------------------------------------------------------------------------------------------------------------------

Basically the econ just offers a tune for regular fuel and to read codes, while the max performance adds the premium tune option as well as a few other things such as a fan cooling option, rev limit and speedometer options for non stock tire/wheel sizes. The price difference is only $30 between the two.

Gotchya, seeing that line I thought it was your sig and read right over it haha

Yeah, if I had to choose, the max energy is the one I'd go with. Did you ask about where they got the hp/tq for that liberty? Since we have the same engine those numbers appear wrong

I didn't ask him and probably would get an answer like "that's what we dyno'd it at". I figure I will test it out for a few weeks and return it if I do not notice any tangible results. There is a 15% re-stocking fee with autoanything, and I received a 10% discount so it will only cost me $20 or so to test it out and send it back if I don't like it.
